Bug Description

SRU Justification:

Impact: the wireless layer is not connected to ftrace anymore

How to reproduce: see the generated .config

Fix: enable again MAC80211_DRIVER_API_TRACER (see the attached patch)

=====

ftrace hooks for the mac80211 layer were mistakenly compiled out during b30fb19 ("Quiet ieee80211 debugging")

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
